Fonts Not Updating in Webflow After Importing Relume Wireframe

HI, i just imported my Relume wireframe into Webflow, using Webflow's plugin, after first cloning the Relume Stylesheet in Webflow. I changed all of my fonts in the Webflow stylesheet, however most of my fonts aren't updating in my Relume wireframe pages. I changed the fonts in 3 areas in the stylesheet, the header fonts, the HTML fonts, and the Rich text fonts. For the fonts that aren't working, they say "system-ui" instead of my chosen font. Has anyone here had this issue or know how to fix?
